cannot create network - followed guide and it just doesn't work...

[bruteForce93]

Error response from daemon: driver failed programming external connectivity on endpoint zu-controller (560ebca05d7a90e644a074bf66e82a1bcba190eb5a3c9c0df0c86dd30560bdac): Error starting userland proxy: listen udp4 0.0.0.0:9993: bind: address already in use

I can login but pressing on create new network button does absolutely nothing. Can anybody help out?

I think you are already having zero tier running , make sure to remove it or

edit the docker-compose.yml

like in

zerotier:
image: zyclonite/zerotier:1.10.6
container_name: zu-controller
restart: unless-stopped
volumes:
- ./zerotier-one:/var/lib/zerotier-one
environment:
- ZT_OVERRIDE_LOCAL_CONF=true
- ZT_ALLOW_MANAGEMENT_FROM=0.0.0.0/0
expose:
- "9993"
ports:
- "9993:9993"

here change 9995
i.e.

zerotier:
image: zyclonite/zerotier:1.10.6
container_name: zu-controller
restart: unless-stopped
volumes:
- ./zerotier-one:/var/lib/zerotier-one
environment:
- ZT_OVERRIDE_LOCAL_CONF=true
- ZT_ALLOW_MANAGEMENT_FROM=0.0.0.0/0
expose:
- "9993"
ports:
- "9995:9993"

and one more edit at

environment:
- ZU_CONTROLLER_ENDPOINT=http://zerotier:9995/
- ZU_SECURE_HEADERS=false
- ZU_DEFAULT_USERNAME=admin
and that's it

It should work after words
